How to merge audio files online
- Add your files — drop two or more audio files; they can be different formats and sample rates.
- Set the order — drag the rows, or use the arrows on mobile. Top plays first.
- Merge — download the joined result as lossless WAV or compact MP3.
Mix any formats together
You can merge an MP3 with a WAV and an M4A in one go. Each file is decoded with the Web Audio API and automatically resampled to a common sample rate and channel layout before the tracks are joined back-to-back. Everything happens locally on your device — there's no upload, no queue, and no per-file limits.
Common uses
- Stitching podcast segments — intro, interview, outro — into one episode.
- Combining voice memos recorded across several sessions.
- Joining song sections exported from a DAW without reopening the project.
FAQ
Can I merge files in different formats?
Yes. An MP3, a WAV and an M4A can be merged in one go — each file is decoded and automatically resampled to a common sample rate and channel layout before joining.
Is there a limit to how many files I can merge?
No fixed limit. All files are held in your device's memory, so dozens of normal-length tracks are fine on a modern device.
Will there be gaps or clicks between tracks?
Tracks are joined back-to-back with no added silence. If a source file starts or ends abruptly you may hear a click — trim the edges first for a cleaner splice.
